To all whom it may concern:

Be it known that I, CHARLES BERGENER, of

Letters Patent No. 262,247, dated April 17,

My present invention relates to improvements in that class of lampsadapted to be used on bicycles or other vehicles, is anim provement uponthe lamp shown in my pend- 2o ing application for Letters Patent, SerialNo. 604,996, filed September 5, 1896, and has for its object to improvethe construction and operation of said lamp, whereby the supply of airto the burner beneath the burner-cone will be sufficient to cause themaximum flame whether the lamp be still and liable to be subj ected toblasts of air from any direction or is moving in one direction andsubjected only to the blast caused by the movement of the vehicle; andto these and other ends the invention consists in certain improvementsin construction and combinations of parts, all as will be hereinafterdescribed, and thenovel features pointed out particularly in the claims3 5 at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a lampconstructed in accordance with my invention; Fig. 2, a plan View of thesame with the top section re- 0 moved; Fig. 3, a central verticalsectional View; Fig. 4, a horizontal sectional view on the line so a; ofFig. 3; Fig. 5, a vertical sectional view on the line y 'y of Fig. 2;Fig. 6, a sectional view on the line a 20f Fig. 2, show- 5 ing thebottom portion of the central section of the lamp only; Fig. 7, asection on the line a b of Fig. 5, looking upward; Fig. 8, a sec= tionon the line 0 d of Fig. 2.

Similar reference-numerals in the several figures indicate similarparts.

As in the lamp shownin my prior application, the present inventionembodies generally a tubular body 1, having a removable top 2,'connectedto the body by a bayonet or other suitable catch, as shown, and at thebottom a removable oil-pot 3, having an upwardly-extended perforatedflange 4, entering a correspondingly-perforated flange 5 on the body,the flanges being connected by studs 6, entering suitable slots formedin one of the flanges, whereby an air-space will be formed between thetop of the oil-pot and a plate 9 in the body.

8 indicates an ordinary slip-burner resting in the oil-potand heldinposition by having its upper portion engaging with a bottom plate 9,between which and the burner-cone 10 is formed an air-chamber 11. At therear of this air-chamber is an upwardly-extending air-tube 12, having aninjector 13 at its upper end, and suitable holes 14 are provided in theupper portion of the body opposite the entrance tothe injector. Thefront of the body is provided with a gogglelo, in which is located awindow, or, preferably, a lens 16, and behind the burner is a removablereflector 17. The sidesof the body are also provided with the usualwindows 18, one or both of which is adapted to be opened for the purposeof lighting the wick. 1

Extending around the body of the lamp and preferably in the plane of theinjector 13 is an air-director composed of plates 19 and 20. Thechannels in the top and bottom of this director and the passage betweenthe overhanging edges of the two plates communicate with the end of theinjector 13, as in my prior application.

21 indicates tubes extending Vertically on opposite sides of the goggleor front of the lamp and communicating at their lower ends with theair-chamber 11 beneath the burnercone. Their extreme upper ends areclosed, though openings are formed in the sides next the body into whichthe edges of the plates 19 and 20 enter, and in the upper end of thesetubes are provided small dividing-plates 22, extending part way acrossthe air-passage formed between the plates 19 and 20 of the air-directorand extending below said director a short distance between the tube andthe body of the lamp, as shown particularly in 7 Figs. and 7, theconstruction being such that as the lamp moves forward a portion of theair in the central channel of the annular air-director and beneath thesame will be delatter, so that there will always be a sufficient supplyof air beneath the burner-cone to support combustion and produce themaximum flame.

In order that the air passing down the tube 12 may not impinge directlyupon the flame, I provide in the chamber 11 a perforated guard ordeflecting plate 23, extending partially around the burner-opening andbetween the latter and the opening of the rear tube 12 and connectingwith the body at the sides, whereby the current of air descendingthrough the tube 12 will not impinge directly upon the flame, but willbe divided and distributed in the chamber in the best manner. The exactlocation and construction of this deflecting-plate 23 is not essential,excepting that it shall be disposed in such manner as to prevent thedirect blast of air from tube 12 upon the flame, although I prefer thearrangement shown, as I find in practice that it is desirable.

The sides of the lamp-body 1 are perforated at 26 in order to afford asupply of air above the burner-cone, and inside of the bodyIarrangevertical plates 27 to'prevent the air entering these perforations fromimpinging directly upon the flame.

I do not claim herein the construction of the lower part of thelamp-body and the oil-pot attached in the manner described, as this isclaimed in my pending application, Serial No. 611,385, nor do I claimherein the combination of the body, director, and a single air-tube atthe rear having the injector at the top, as this is claimed in mypending application, Serial No. 604,996.

I claim as my invention 1. In a lamp, the combination with the body, theburner, the burner-cone, and the air-chamber beneath the burner-cone, ofthe rear air-tube separated from the body and having the injector at itsupper end and communicating with the air-chamber, and the side tubesclosed at their upper ends and also connected to the air-chamber andhaving the openings and the dividing-plates therein, substantially asdescribed. v

2. In a lamp, the combination with the body having the window at thefront, and the air-tube at the rear separated from the body and havingthe injector at the top, of the burner and its cone, the air-chamberbeneath the cone with which the rear tube connects, the air-directorextending around the lampbody,the separate side tubes having the closedupper ends and connected with the air-chamber and having the openings inproximity to the air-director, substantially as described.

3. In a lamp, the combination with the body, the burner and cone, andthe air-chamber beneath the latter, of the rear air-tube separated fromthe body, having the injector at its upper portion and communicatingwith the air-chamber and also with the body above the burner, the sidetubes closed at their upper ends and open near said ends on the sidenext the body and having the dividing-plates in said openings, and anannular air-director cooperating with the side and rear tubes.

4. In a lamp, the combination with the body having the window at thefront, the burner, the burner-cone, and the air-chamber beneath thecone, of the rear air-tube having the injector at its upper end, theair-director having the upper, lower and intermediate air-channels, theside tubes connected to the air-chamber having the openings at theirupper ends, and the dividing-plates in the openings, substantially asdescribed.

5. In a lamp, the combination with the lamp-body having the window, theburner, burner-cone, and the air-chamber beneath the latter, of the sideair-tubes having the closed upper ends and communicating with theairchamber and open at their upper por tions on the sides next thelamp-body, the vertical dividing-plate in said openings, and thehorizontal air-director having an annular passage and the channeledlower side, substantially as described.
